It looks like we weren't the only ones who were left completely shocked by Cheryl Cole and Jean-Bernard Fernandez-Versini's Caribbean wedding.

The singer's X Factor team were reportedly so taken by surprise they thought it was a prank.

According to Digital Spy, they didn't believe the 31-year-old star had wed her French fella after three months.

It was only when she shared the shot of her blinging wedding band that they realised it was the real deal.

"Everyone thought it was a prank when we saw it in the paper. It truly was the best kept secret in showbiz," a source told the website.

"Jean-Bernard has come down to auditions before and he's a very nice guy. We're very happy for Cheryl and we're sure the judges will be sending out flowers and planning something fun for the arena auditons."

The former Girls Aloud star shared her happy news on Instagram earlier this week - 7 days after they tied the knot.

“I usually do not discuss my personal life but to stop the speculation I want to share my happy news... Jean-Bernard and I married on 7/7/14,” she said in the statement.

The Crazy Stupid Love singer added: “We are very happy and excited to move forward with our lives together.”

She also posted the snap of a giant stone on her ring finger on Instagram.
